Treatment-experienced patient with Roux-en-Y gastric bypass successfully treated with sofosbuvir/velpatasvir/voxilaprevir: A case report.

Purpose: The purpose of this article is to describe a patient with chronic hepatitis C virus (HCV) infection, who had previously taken 2 other direct-acting antiviral (DAA) regimens and undergone Roux-en-Y gastric bypass (RYGB), successfully treated with a sofosbuvir/velpatasvir/voxilaprevir regimen.

Summary: A 64-year-old, African American male presented for management of HCV genotype 1a infection after 2 failed courses of treatment. The patient had a history of severe gastroesophageal reflux disease (GERD), and he was unable to discontinue proton pump inhibitor (PPI) use during all treatment regimens.

New set-up for capillary isoelectric focusing in uncoated capillaries.

Substituted aminomethylphenol dyes, low-molecular-mass isoelectric point (pI) markers and hemoglobin samples from normal individuals and diabetic patients were used to test a new set-up of capillary isoelectric focusing (cIEF) in uncoated capillaries. In previous cIEF methods, a mixture of sample components and carrier ampholytes was applied in the capillary and analyzed. In the new set-up a fractionated injection protocol is used to apply a 'sandwich' ampholyte-sample-ampholyte plug in the capillary for analysis.

[Experience with the molecular genetical detection of the chimera gene of the Philadelphia chromosome].

Molecular genetical techniques could be developed for detection of the chimera gene of Philadelphia chromosome or that of its gene product, due to the relatively conserved structure of the chimera gene. The authors successfully analysed 123 blood/bone marrow samples from 106 patients using these molecular techniques adapted from the literature. Patients were classified by the first diagnosis, 65 CML, 7 AML, 13 ALL patients were studied.

[Importance of the detection of minimal residual disease in the management of acute leukemia].

Between 1984-1988, 57 adult acute leukemic patients were treated with intensive combined chemotherapy in the National Institute of Haematology and Blood Transfusion. For the evaluation of response to therapy, 4 investigations were performed in parallel: bone marrow aspirate, bone marrow biopsy, cytogenetic analysis and bone marrow culture. Nonparametric test for samples taken for the evaluation of remission status showed that bone marrow biopsy was significantly the most sensitive method for the detection of residual disease.

Stromal cell growth and blast colony-forming cells in AML bone marrow.

Bone marrow cells (BMC) from normal donors and from patients with acute myeloid leukaemia (AML) were cultured. Growth kinetics and the efficiency of stromal layers in supporting the adhesion of normal blast-colony forming cells (BL-CFCs) were studied. BMC from treated AML patients formed confluent stromal layers faster than normal BMCs.
